[0002] RF cable, also known as coaxial cable, is composed of coaxial inner conductor, outer conductor and medium supporting inner and outer conductor. RF cable is an important equipment in radio communication, radio and television RF transmission. If it is not selected properly, it will not only cause waste and increase investment cost, but also make the system unstable during operation, cause failure and damage equipment. In order to correctly select RF cable, it is necessary to learn about some characteristic parameters and types of cables. The characteristics of RF cable include electrical performance and mechanical performance. Electrical performance includes characteristic impedance, transmission loss and its frequency characteristics, temperature characteristics, shielding characteristics, rated power and maximum withstand voltage. Mechanical performance includes minimum bending radius, weight per unit length, maximum allowable tension, and aging characteristics and consistency of cable. When selecting RF cable, its characteristic impedance, rated power, attenuation and maximum working voltage that can be tolerated should be considered. In radio communication, radio and television RF transmission, it is necessary to combine the RF impedance, output power and possible peak voltage output by the transmitter, and leave a certain margin. Combined with the environmental conditions of use, select the appropriate cable.

The cable core is prone to slippage inside the cable, causing a short circuit in the cable, which cannot meet the needs of the actual use environment.
